United States Patent 3,533,228 WATCH Zeno Hurt, Mohlin, Switzerland, assignor to Agon Uhrenfabrik Robert Triebold A.G., Mumpf, Switzerland, a company of Switzerland Filed May 6, 1969, Ser. No. 822,177 Claims priority, application Switzerland, Dec. 24, 1968, 19,267/68 Int. Cl. G04b 19/20 U.S. Cl. 58-125 2 Claims ABSTRACT OF THE DISCLOSURE Watch with coaxial minutes and hours discs with colored indications arranged so that errors in reading can be avoided by correlating the colors of the indications.

The watch of the present invention has at least two co-axial discs carrying indications of the minutes and hours.

Numerous watches of this type are known and are generally provided with an hours disc jumping upon passage of the minutes disc by zero.

These watches have the disadvantage of being difficult to read especially during time where the minutes disc passes the zero because at this moment an error in reading the hour is possible.

The watch of the invention aims to avoid these disadvantages. It is characterized by the fact that the indications carried by the hours disc are successively repeated and colored in two different colors and that the indications carried by the minutes disc are divided into two zones successively of different colors, the first going from zero to 29 minutes and second from 30 to 59 minutes, the said different colors being successively the same.

The accompanying drawing represents by way of example an embodiment of the coaxial discs of a watch according to the invention.

The coaxial discs of the watch shown in the figure of the drawing are the following: 1 designates the minutes discs, 2 the hours discs and 3 the optional day disc. The indications of these discs are visible through windows 1a, 2a, 3a of a dial not shown.

The minutes disc 1 has two zones differently colored; a first zone goes from 0 to 29 minutes and is for example colored blue; the second zone goes from 30 to 59 minutes and is colored red.

The reading of this dial is extremely simple. In the hour dial there always appear two different numbers of different color. In the example shown in the drawing, the visible hour indication 2 is in blue and 1 is in red. To determine to which hour corresponds the minute marked by the index 4 (here the minute 0 is blue), this blue color is made to correspond with the figure having this color in the window 2a, thus the hour indicated is exactly 2 oclock.

As can be seen, the reading of this dial is extremely simple. This dial can be provided with a central needle indicating the seconds and, as indicated in the drawing, with a coaxial dial indicating the day.

What is claimed is:

1. A watch having a dial and at least two coaxial rotatable discs one carrying indications of 0 to minutes and the other carrying indications of 1 to 12 hours, characterized by the fact that each of the hour indications carried by the hours disc is repeated to provide two successive occurrences of each hour indication, said hour indications being colored in two different colors, the first occurrence of each hour indication being of a first color and the second occurrence being of a second color and that the indications carried by the minutes disc are divided into two successive zones of said different colors; the first zone going from 0-29 minutes being of said first color and the second zone going from 30 to 59 minutes being of said second color.

2. Watch according to claim 1, provided on its dial with a window for reading the indication on the minutes disc and a window for reading indications of the hours disc, said window for the hours disc showing two successive indications of different color.
